TestPrepUnlimited , could you please explain how \(\sqrt{\frac{1.2}{0.09}}\) becomes \(\sqrt{\frac{40}{3}}\)? Thanks!

Hi sjuniv32

\(\sqrt{\frac{1.2}{0.09}} = \sqrt{\frac{12}{10}*\frac{100}{9}} = \sqrt{\frac{120}{9}} = \sqrt{\frac{40}{3}}\)

I hope its clear your query

All the responses above are great! When looking at numbers it is important to "see through" them and look at the significant digits. When we see \(\frac{1.2}{0.09}\) we actually want to look at 12 and 9. So the first step is to have \(\frac{120}{9}\) then simplify from there.
